Why do chronic dieters often violate their dieting goals? One possibility is that they experience stronger hedonic responses to tempting food than normal eaters do. We scrutinized hedonic processing in dieters and normal eaters (a) by manipulating food preexposure and (b) by assessing both immediate and delayed hedonic responses to tempting food with an adapted affect-misattribution procedure. Without food preexposure, dieters showed less positive hedonic responses than normal eaters (Study 1). When preexposed to tempting-food stimuli, however, dieters exhibited more positive delayed hedonic responses than normal eaters (Studies 1 and 2). Furthermore, delayed hedonic responding was meaningfully related to self-reported power of food and state cravings (Study 2). These findings suggest that dieters experience difficulties in down-regulating hedonic affect when in a "hot" state and that self-regulation research may benefit from a greater emphasis on temporal dynamics rather than static differences. 相似文献

Sexual assault as defined by law, psychiatry and sociological research is contrasted to the everyday definition of rape. Official figures on the frequency of sexual assaults as communicated in annual reports by the police differ greatly from figures found by research on sexual victimization or representative studies using different definitions of violence and abuse in sexual relations. Overpowering and violence is not a rare phenomenon in sexual relations – nearly every second woman and 10% of men are familiar with such situations. There are not only biological conditions (individual variance in neurophysiological parameters) but also psychological conditions favoring the use of power and threat instead of courting in sexual partnerships. External conditions are certain popular opinions in parts of society and certain subcultures which may also be more or less in favor of male superiority, thus helping the perpetrator to justify his assault or on the contrary helping the victim to find support in court procedures and therapy if necessary. Prevention therefore has two targets: a general one by changing popular opinions which are in favor of the use of power in sexual relations and informing persons in danger of becoming victims about the risks and the possibilities to protect themselves and an individual one by treating victims to overcome their psychological injuries and to treat perpetrators inside and outside the judicial system. The current discussion on increased availability of pornography in the internet shows both aspects: a general target to reduce negative influences of pornography which produces devaluating views on sexuality and women and the more individual task of tackling new forms of pathology created by the media at least for some of the consumers. 相似文献

The paper reconstructs the read thread that links the information revolution, the information concept and information ethics in Floridi’s philosophy of information. In doing so, it acknowledges the grand attempt but doubts whether this attempt is up to the state of affairs concerning the actual point human history has reached. It contends that the information age is rather conceivable as a critical stage in which human evolution as a whole is at stake. The mastering of this crisis depends on an appropriate shaping of Information and Communication Technologies which requires ethical considerations. In this respect, Floridi’s notion of the fourth revolution, his assumption of the management of the life cycle of information, and his ontocentric macroethics will be discussed in the light of the term “scientific-technological revolution”, the idea of a noogenesis, a new way of thinking and new weltanschauung, the concept of friction in social and physical aspects, the concept of collective intelligence and its application to the Internet and last, but not least, the vision of a Global Sustainable Information Society. 相似文献

The categorization of sadism has turned out to be a versatile phenomenon, which covers a spectrum from harmless symbolic rituals to extremely violent acts where strong impulses or prolonged fantasies and rituals are involved. As the phenomenon is versatile its causes and appearances vary as well, although so-called BDSM (bondage & discipline & dominance & submission & sadism & masochism) practitioners and persons with severe sadism in a forensic context share only few common preferences. Based on own clinical experiences with sadism in forensic patients the authors support the proposed revision of the Diagnostic and Statistical Manual of Mental Disorders (DSM-V) especially the diagnostic disjuncture of sadism and masochism. Sexual sadism appears more frequently in forensic contexts in combination with sadistic, antisocial and borderline personality disorders but rarely with masochism. Masochism is otherwise reported to be more prevalent in patients of general psychiatry, however, combined with depression or dependent personality traits rather than with sadism. Moreover, the authors believe that if use of the diagnostic term sadism is perpetuated the establishment of the proposed new diagnosis “paraphilic coercive disorder” is unnecessary. The diagnostic term is also important for treatment and assessment. Despite the lack of reliable long-term studies with larger samples, it is reasonable to assume that medication, sometimes even anti-androgenic treatment, can be indicated in patients with severe sadism. 相似文献

Logic-based XML data integration: a semi-materializing approach 总被引:1,自引:0,他引:1
Wolfgang May 《Journal of Applied Logic》2005,3(2):271
We first describe the approach to XML data integration in the XPathLog/LoPiX project that uses a warehouse strategy. We show that the DOM model and the XML Query Data Model are not suitable for this task since the integrated database is not necessarily a tree, but a set of overlapping (original and integrated) trees. The problem is solved by using a node-labeled graph-based data model, called XTreeGraph, for the internal XML database that represents multiple, overlapping XML trees, or tree views.In the second part, we return to the standard XML data model—by still keeping the overlapping tree idea by “simulating” it: The data is internally represented by XML where the “overlayed” resulting tree is represented by XLink elements that refer to the original sources. By using a logical, transparent data model for XLinks as investigated in [May, in: 11th WWW Conference, 2002], all queries behave as stated against the XTreeGraph. The use of links for partial materialization also turns the approach from a warehouse approach into a mixed approach that combines the advantages of the warehouse approach and of the virtual approach. The approach is again illustrated by using XPathLog as data integration language. 相似文献

The present paper reports a case study about public deliberations in three Israeli kibbutzim regarding a disputed school issue: whether to maintain a traditional in-kibbutz high school despite a heavy financial burden or to close it and send kibbutz youths to a public regional school The results served as a demonstration of a 'thinking group' (i.e. of how the collective aims of a group are achieved by the coordinated rhetorical behaviour of individuals according to the formal rules of the collective deliberations). First, video-recordings of six general assembly meetings in which the issue was discussed was analyzed as to their argumentative content. Second, the extracted arguments were presented to a sample of 342 kibbutz members to capture the distribution of opinions in the population. It is proposed that most kibbutz members were willing to preserve their collective living and saw the closure of their in-kibbutz school as a threat to their traditional collective identity. We observed a distinct form of public rhetoric during the deliberations in the general meetings which provides a podium for the disputed opinions, preserves the kibbutz shared identity representation and avoids social friction. 相似文献

This study examined the effects of relationship characteristics, as measured by Rusbult's (1980) investment model, on safer‐sex behavior between steady gay male partners. Analyses showed that low satisfaction with the relationship was associated with more risky unprotected anal intercourse (UAI). High commitment to the relationship was associated with more practice of negotiated safety (i.e., having safe UAI after both partners have tested negative for HIV and have reached sexual safety agreements). High relationship investment was associated with more risky UAI (borderline significant). We conclude that using relationship satisfaction, commitment, and investment as co‐determinants of sexual risk behavior could prove useful in the development of new HIV‐prevention strategies for gay men in relationships. 相似文献

Psychological theories of weight regulation are based on homeostatic feedback assumptions. They mostly attribute the cause of overweight and obesity to lowered sensitivity to internal hunger and satiety cues. Based on the assumption that human food consumption in food-rich environments is increasingly driven by pleasure rather than need for calories, a goal conflict theory of hedonic eating is presented. This theory is not only supported by the outcome of our own research programme but can also account for findings of the research conducted in the context of other psychological theories. Some implications for weight loss strategies are discussed.
Les théories psychologiques sur la régulation du poids sont basées sur des hypothèses d'une rétroaction homéostasique. Elles attribuent généralement la cause de la surcharge pondérale et de l'obésitéà une sensibilité interne amoindrie à la faim et aux indicateurs de satiété. Reposant sur l'hypothèse que la consommation alimentaire humaine dans des environnements riches en nourriture est de plus en plus guidée par le plaisir plutôt que par le besoin de calories, une théorie "goal conflict theory of hedonic eating" est présentée. Cette théorie qui ne s'appuie pas seulement sur les résultats de notre propre programme de recherches, peut aussi expliquer les résultats d'études réalisées dans le cadre d'autres théories psychologiques. Des implications concernant des stratégies de perte de poids sont discutées. 相似文献

Early periventricular brain lesions can not only cause cerebral palsy, but can also induce a reorganization of language. Here, we asked whether these different functional consequences can be attributed to topographically distinct portions of the periventricular white matter damage. Eight patients with pre- and perinatally acquired left-sided periventricular brain lesions underwent focal transcranial magnetic stimulation to assess the integrity of cortico-spinal hand motor projections, and functional MRI to determine the hemispheric organization of language production. MRI lesion-symptom mapping revealed that two distinct portions of the periventricular lesions were critically involved in the disruption of cortico-spinal hand motor projections on the one hand and in the induction of language reorganization into the contra-lesional right hemisphere on the other hand. Both regions are located in a position compatible with the course of cortico-spinal/cortico-nuclear projections of the primary motor cortex in the periventricular white matter, as determined by the stereotaxic probabilistic cytoarchitectonic atlas developed by the Jülich group. 相似文献
